疑问：有关全向告警装置

沙发，等科普。

7）再补充一点：全向告警装置的研制难度在什么地方？有没有代的分法。

俺是超菜菜鸟

请大家帮忙顶一下，一直顶到有大佬肯回答问题为止:(

好，顶，俺只小菜躲在轰炸机旁边等食吃........:time:

火龙老大该打，知道而不说:( :(

;funk 老大，俺要是清楚还能忍住，早满版胡喷了，俺就是看好多JJ这一个疙瘩那一个蒙皮的，也不懂，所以来帮顶的.......:$

再问一下J-10的全向告警装置。。。

手头是有书。。。。问题是我想变成稿子发到杂志上

这个东西说来话长了，RW和MW实现的方法各有不同，四代机传感器综合以后能够用最少的天线完成更多的功能，比如ALR-94，其精度甚至能满足导弹发射初始段定位的需要。

兄台可否多介绍点，还有比如新出来的哪些满身都是眼睛的家伙，是否将相关功能集成到各处的同一个装置上了，就是告警啊，探测啊，识别啊..........

老大，您说的小的不懂啊。什么是RW？什么是MW？

要不您就解答一两个问题先。多谢了

呃！最近某人的车上也要装全向告警装置了！:D

Radar Warning ReceiverTypically fitted to military aircraft, radar warning receivers (RWR) detect the radio emissions of radar systems, whether ground-based or on-board other aircraft. The system is often capable of classifying the source of the radar by type (Pulsed or continuous wave radar, for example) and strength. It may be further capable of using this data to identify the type of threat the detected radar poses, e.g. an incoming radar-guided surface-to-air missile (SAM).The RWR usually has a visual display somewhere prominent in the cockpit (in some modern aircraft, in multiple locations in the cockpit) and also generates audible tones which feed into the pilot's (and perhaps RIO/co-pilot/GIB's in a multi-seat aircraft) headset. The visual display often takes the form of a circle, with symbols displaying the detected radars according to their direction relative to the current aircraft heading (i.e. a radar straight ahead displayed at the top of the circle, directly behind at the bottom, etc.). The distance from the center of the circle, depending on the type of unit, can represent the estimated distance from the generating radar, or to categorize the severity of threats to the aircraft, with tracking radars placed closer to the center than search radars. The symbol itself is usually related to the type of radar or the type of vehicle that carries it, often with a distinction made between ground-based radars and airborne radars. Audible tones are usually assigned to each type of threat or type of radar and are fairly distinctive. The more serious the threat, the more shrill the tone in order to get the pilot's attention. For example, an active missile seeker might be a high pitched, almost continuous trill whereas the radar of an obsolete fighter type or SAM system might be a low pitched, intermittent buzz.The RWR is useful for identifying, avoiding, evading or engaging threats. For example, a fighter aircraft on a combat air patrol (CAP) might notice enemy fighters on the RWR and subsequently use its own radar set to find and eventually engage the bandit. In addition, the RWR helps identify and classify threats - it's hard to tell which blips on a radar are dangerous, but since different fighter aircraft typically have different types of radar sets, once they turn them on and point them near the aircraft in question it may be able to tell, by the direction and strength of the signal, which of the blips is which type of fighter.A non-combat aircraft, or one attempting to avoid engagements, might turn its own radar off and attempt to steer around threats detected on the RWR. Especially at high altitude (more than 30,000 feet AGL), very few threats exist which will not be giving out radiation. As long as the pilot is careful to check for aircraft that might try to sneak up without radar, say with the assistance of AWACS or GCI, it should be able to steer clear of SAMs, fighter aircraft and high altitude, radar-directed AAA.SEAD and ELINT aircraft often have very powerful RWR equipment like the U.S. HTS (HARM targeting system) pod which is able to find and classify threats which are much further away than those detected by a typical RWR, and may be able to overlay threat circles on a map in the aircraft's multi-function display (MFD), providing much better information for avoiding or engaging threats, and may even store information to be analyzed later or transmitted to the ground to help the commanders plan future missions.The RWR can be an important tool for evading threats if avoidance has failed. For example, if a SAM system or enemy fighter aircraft has fired a missile (for example, a SARH-guided missile) at the aircraft, the RWR may be able to detect the change in mode that the radar must use to guide the missile and notify the pilot with much more insistent warning tones and flashing, bracketed symbols on the RWR display. The pilot will then know to take evasive action, and what type of evasive action to take, in order to break the missile lock or dodge the missile. The pilot may even be able to visually acquire the missile after being alerted to the possible launch. What's more, if an actively guided missile is tracking the aircraft, the pilot can use the direction and distance display of the RWR in order to work out which evasive maneuvers to perform in order to outrun or dodge the missile. For example, the rate of closure and aspect of the incoming missile may allow the pilot to determine that if s/he dives away from the missile, it will be unlikely to catch up, or if it is closing fast, that it is time to jettison external supplies and turn toward the missile in an attempt to out-turn it.

Example of a RWR display
This is what a RWR display might look like and is particularly repesentative of the AN/ALR-69. It shows a ground-based search radar nearly straight ahead, an SA-6 SAM system about 30 degrees to the right of straight ahead (currently the closest and most dangerous threat as indicated by the diamond and hat) and an F-15 fighter behind and slightly to the left. The distance of the threats from the centre is not necessarily indicative of the threat's absolute range, but rather the proximity to the lethal envelope of the threat. For example, if an SA-2 and a ZSU-23-4 are both dead ahead of the aircraft and at the same range, the SA-2 will actually appear nearer to the centre of the display because the SA-2 has a much greater lethal envelope than the ZSU-23-4. The concentric rings on the display signify different 'lethality zones'. The outer ring signifies that the threat is beyond engagement range (ie the range it can engage you, not vice versa), the middle ring signifies that the threat is within engagement range, the inner ring equates to a 'no-escape' zone. In the example below, the SA-6 and F-15 are both well within the engagement zone and on the borderline of the 'no-escape' zone. This ordering of the rings applies to the AN/ALR-69 found in, for example, the F-16. However, some sources claim the order is reversed on the AN/ALR-67, with the 'critical' zone being the outer ring. In many ways this would make more sense, because it allows greater spacial separation of the highest priority threats on the display, allowing the pilot a greater degree of angular resolution when determining the direction of the threat.
